Where should I put the log4j.properties file?

Question

I know it's a bit late to answer this question, and maybe you already found the solution, but I'm posting the solution I found (after I googled a lot) so it may help a little:

1. Put log4j.properties under WEB-INF\classes of the project as mentioned previously in this thread.
2. Put log4j-xx.jar under WEB-INF\lib
3. Test if log4j was loaded: add -Dlog4j.debug @ the end of your java options of tomcat

Hope this will help.

As already stated, log4j.properties should be in a directory included in the classpath, I want to add that in a mavenized project a good place can be src/main/resources/log4j.properties

You can specify config file location with VM argument -Dlog4j.configuration="file:/C:/workspace3/local/log4j.properties"

You have to put it in the root directory, that corresponds to your execution context.

Example:

    MyProject
       src
           MyClass.java
           log4j.properties

If you start executing from a different project, you need to have that file in the project used for starting the execution. For example, if a different project holds some JUnit tests, it needs to have also its log4j.properties file.

I suggest using log4j.xml instead of the log4j.properties. You have more options, get assistance from your IDE and so on...

For a Maven Based Project keep your log4j.properties in src/main/resources. Nothing else to do!

If you put log4j.properties inside src, you don't need to use the statement -

PropertyConfigurator.configure("log4j.properties");

It will be taken automatically as the properties file is in the classpath.

Try:

PropertyConfigurator.configure(getClass().getResource("/controlador/log4j.properties"));
